Inkqubo ye-NVM Express ivela kwi-OS X Yosemite 10.10.3

Uhlaziyo lwamva nje lwe-OS X Yosemite 10.10 ifika ngenkxaso yeNVM Express (NVMe), Inkqubo entsha ethatha ithuba elingcono lomthamo weeyunithi zokugcina ze-SSD.

Uninzi lwezi yunithi ezisetyenziswayo ngoku Umgangatho we-AHCI, oqala ngo-2004. Umgaqo-nkqubo we-AHCI wawuyilelwe ukugcina imithombo yeendaba yokugcina izinto eziphezulu kwaye ezi zixhobo zintsha zinofikelelo olukhawulezayo lokufunda / ukubhala ngokucacileyo zazingajoliswanga, zisenza ukuba kube nzima ukufumana uninzi kuzo zonke iimeko.

Inkqubela phambili kugcino olungenakho ukuguquguquka njengeenkumbulo ze-NAND kunye ne-MRAM zikhokelele kumzi-mveliso ukuba uphuhlise ujongano olungcono lwesoftware ukulungisa imida ye-AHCI kwaye uqhubeke.

Iziphumo zale nguqulelo zifunyenwe kwi-NVMe, isifinyezo sokuchaza uhlobo lweememori ezingacacanga kwaye eziye zaphuhliswa liqumrhu elinamalungu angaphezu kwama-80, uphuhliso belukhokelwa ziingxilimbela ezifana ne-Intel, i-Samsung kunye ne-LSI. I-NVMe yakhelwe ngokukodwa i-SSD kunye ne-PCIe ye-NVMe ujongano, le protocol yenzelwe ukuba ikwazi ukuhlangabezana neemfuno zeshishini njengoko sisiya kubuchwephesha bememori bexesha elizayo, oko kukuthi, siyakubona ukuba kuthatha njani izintso zeRRAM kunye neMRAM yexesha elizayo. eya kwaziswa kwimakethi yokugcina ngaphambi ko-2020.

Olona ncedo lukhulu kwi-NVMe Ukubambezeleka kwayo okuphantsi kwee-2,8 microseconds xa kuthelekiswa nee-microsecond ezi-6,0 ze-AHCI. Ndiyabulela kule latency isezantsi, ixesha lokusetyenziswa kwediski liya kuncipha, ikhompyuter iya kuchitha ixesha elininzi ingasebenzi kwaye ke oko kuya kunceda ngokuyinxalenye ukufumana ixesha elide lobomi bebhetri. Ukongeza, kunokubakho iimeko ezithile apho inkxaso ebhetele yesoftware njengoko uphuhliso lweprotocol luqhubeka ukunceda ngokusebenza.

Isixhobo sokuqala sika-Apple ekuxhaseni le teknoloji yiyo iMacBook entsha eyi-intshi ezili-12 Ukongeza ekubeni kunokwenzeka ukuba izixhobo ze-Apple ezizayo ziya kuyonwabela i-NVMe.
